The boiling points of five liquids have been measured 10 times each by a team of scientists, with fairly consistent results. Which next step would be the most logical? 1. Test a sixth liquid to see if it follows patterns in the rest of the data.

2. Use a new thermometer to make sure that the original one was not faulty.

3. Continue collecting data until exact boiling points can be found.

4. Test the results an eleventh time, and average the new trial into the data.
